20100051324DIELECTRIC SUBSTRATE WITH HOLES AND METHOD OF MANUFACTURE - An aspect of the present invention comprises a method of forming holes in a dielectric substrate comprising the steps of applying a layer of photoresist to a dielectric substrate, exposing portions of the photoresist to actinic radiation through a photomask to form a pattern in the photoresist for an array of holes to be etched in the substrate, developing the photoresist, etching the dielectric substrate to form an array of holes, each hole extending at least partially through the dielectric substrate, and removing the excess photoresist. Another aspect of the present invention is a method of simultaneously forming holes in a dielectric substrate some of which extend partially through the substrate and some of which extend completely through the substrate. Other aspects of the present invention are dielectric substrates formed using the methods of the invention.03-04-2010
20100149408ACCESSORY AND ACCESSORY FOR IMAGE PICKUP APPARATUS - An accessory and an accessory for an image pickup apparatus are provided and are advantageous in reducing cost by reducing the number of parts. A retaining ring is engaged in an annular groove formed in an outer circumference of a cylindrical part of a wide-angle converter lens. Each of retaining ridges has a bottom wall extending from the inner circumference of the annular part in the direction of the width of the annular part in a recess, and a protruded wall extending radially outward of the annular part from the end of the bottom wall, spaced from the annular part, and protruding radially outward from the first outer circumference. When the parts, provided with the retaining ridges, of the annular part are depressed radially inward of the annular part, the protruded wall sink radially inward from the first outer circumference.06-17-2010

20080249257Latent curing agent for epoxy resin and method for manufacturing the same - A latent epoxy resin curing agent is provided which can be manufactured without using an amphiphilic polymer compound requiring a painful trial and error selection process, exhibits excellent solvent resistance and low-temperature fast-curing ability, and contains an imidazole-based compound as a main component. In the latent epoxy resin curing agent containing the imidazole-based compound as a main component, adduct particles formed through adduct reaction of an epoxy-based compound with the particulate imidazole-based compound are coated with an ethyl cellulose film. Furthermore, the surfaces of the adduct particles may be crosslinked with a polyfunctional isocyanate compound. A mixture of the epoxy-based compound, the particulate imidazole-based compound, and ethyl cellulose in a predetermined saturated hydrocarbon-based solvent is heated under stirring. Then, the epoxy-based compound and the particulate imidazole-based compound are subjected to adduct reaction to give a slurry of the adduct. After the slurry is cooled, the latent epoxy resin curing agent is filtrated. If necessary, the ethyl cellulose film is crosslinked with a polyfunctional isocyanate compound.10-09-2008

Then, the epoxy-based compound and the imidazole-based compound are subjected to adduct reaction to obtain a slurry of the adduct. After the slurry was cooled, the polyfunctional isocyanate compound is added thereto to crosslink the ethyl cellulose film.10-09-2008
20090152504Latent Curing Agent - An aluminum chelate-based latent curing agent is provided which can cure a thermosetting epoxy resin at a relatively low temperature in a short period of time. A method for producing such an aluminum chelate-based latent curing agent, whose curing conditions can be relatively easily controlled, is also provided. The aluminum chelate-based latent curing agent is made latent by reacting a silsesquioxane-type oxetane derivative with an aluminum chelating agent in the presence of an alicyclic epoxy compound.06-18-2009
20090230360Latent Curing Agent - An aluminum chelate-based latent curing agent, which can cure a thermosetting epoxy resin at a relatively low temperature in a short time, is made latent by reacting a silsesquioxane-type oxetane derivative with an aluminum chelating agent in the presence of an alicyclic epoxy compound, and then further reacting the resultant mixture with a liquid epoxy resin and an imidazole compound or with an aromatic vinyl compound and a radical polymerization initiator.09-17-2009

20110127158MANUFACTURING METHOD OF SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE - In a copper damascene wiring process, a tantalum-based laminated film, which is used as a barrier metal film, is continuously formed in a sputtering deposition chamber. When the continuous deposition process is discontinuously applied to a number of wafers, a tantalum film and a tantalum nitride film which are relatively thin are alternately deposited over an inner surface of a shield in a sputter deposition chamber, which results in a thickness of the deposited film being on the order of several thousand nanometers. The deposited film peels off due to internal stress therein to generate foreign material or particles. To counteract this, a tantalum film, which is much thicker than the tantalum film formed over the wafer at one time, is formed over the substantially inner wall of the chamber at predetermined intervals when repeatedly depositing the tantalum nitride film and the tantalum film in the sputtering deposition chamber.06-02-2011
